I am using this binding configuration on client and server:
<basicHttpBinding>
<binding name="BasicHttpBinding_IService1">
<security mode="TransportWithMessageCredential">
<transport clientCredentialType="Windows" />
</security>
</binding>
</basicHttpBinding>
The client credentials seem to not be passed automagically (or are they?) this way like i assumed, so i need to know how to set them by myself. Will this even work?
You have to enable Windows Authentication on IIS. Look at the below link for how to do it.
Also, I checked the MSDN web site, the key difference between your config and at msdn is security mode
<bindings>
<basicHttpBinding>
<binding name="BasicHttpEndpointBinding">
<security mode="TransportCredentialOnly">
<transport clientCredentialType="Windows" />
</security>
</binding>
</basicHttpBinding>
</bindings>
The only difference is mode as you can see. I am not sure this would solve your problem but give it a go.
Below are the 5 possible “Security Modes” across all “Service Bindings”.
None - Turns security off.
Transport - Uses “Transport security” for mutual authentication and message protection.
Message - Uses “Message security” for mutual authentication and message protection.
Both - Allows you to supply settings for transport and message-level security (only MSMQ supports this).
TransportWithMessageCredential - Credentials are passed with the message and message protection and server authentication are provided by the transport layer.
TransportCredentialOnly - Client credentials are passed with the transport layer and no message protection is applied.
